I don't doubt that that is your experience of it, but that is a very rare view!
To jolly - this topic is regualrly explored on UKC. Consensus is that skiing in climbing boots on anything other than a very gentle incline is exceptionally challenging, and more importantly, a good way to do yourself a really nasty injury. Ski boots offer great stability for climbing but they are a bit heavier. If I wanted to do any downhill skiing in a climbing/skiing day, I'd opt for ski boots every time.
Your other option is to take a mini ski (Rossignol Ventura 99cm) that fits walking/climbing boots well for UPHILL skinning/snowshoeing, but lethal on DOWNHILL.
